Why is my horse’s graze hot, sore, and red?

Overview
A graze that looks hot, sore and red is often just the body’s normal early response to a minor skin injury. It can also happen if the area has been rubbed, contaminated with dirt, or irritated by flies, tack or movement. Most small grazes settle with simple care, but it’s sensible to keep a close eye on how it looks and feels.
Things To Check
1. Check when you first noticed the heat, redness or soreness, and whether it has changed after turnout, exercise, grooming or stabling.
2. Look closely for broken skin, swelling, discharge, scabs, bleeding or any area that seems more painful than the rest.
3. Check whether the graze is in a place that may rub against tack, rugs, bandages or stable fittings.
4. Feel the surrounding area gently to see whether the heat is staying local or spreading beyond the graze.
5. Watch how your horse is moving and behaving. A graze that seems minor but is making them stiff, unwilling to move, or very sensitive deserves more attention.
6. Consider whether mud, bedding, flies or a dirty environment could have made the skin more irritated.
7. Check if there are any signs the wound is not staying clean, such as weeping, dirt sticking to it or repeated picking at the area.
Common Causes
The most common reason is simple inflammation from a fresh graze. Skin often becomes warm, red and a bit sore while it starts to heal.
Rubbing from rugs, tack, leg wraps or repeated movement can make a small graze look angrier than it really is.
Dirt, mud, bedding or sweat can irritate the area and slow down calm healing.
Less commonly, the graze may be developing a local infection, especially if heat, swelling, pain or discharge are increasing rather than easing.
Occasionally, a graze can hide a deeper injury than it first appears, particularly if it was caused by a kick, wire, fence or another sharp edge.
What To Do
Keep the area as clean and dry as you reasonably can. If it’s a minor graze, gently remove surface dirt and avoid scrubbing hard, which can make the skin more sore.
Protect the area from further rubbing or contamination where possible. If turnout, tack or stable gear is likely to irritate it, think about whether the horse needs a temporary change in routine.
Check the graze at least daily so you can spot changes early. It can help to note whether the redness, heat or soreness is improving, staying the same or getting worse.
Keep flies, mud and dirty bedding away from the area as much as you can, especially in warmer weather or wet conditions.
If the graze starts to look more swollen, more painful, or begins to ooze, that’s a good reason to get it checked rather than waiting it out.
When To Contact A Vet
Contact your vet if the graze is getting hotter, redder or more swollen, if there’s discharge, a bad smell, or increasing pain, or if your horse seems dull, off colour, or uncomfortable in themselves.
You should also call your vet if the wound is deep, gaping, near a joint or tendon, caused by a puncture or wire, or if you’re unsure whether it’s more than a surface graze.
